FEMW — Emware Ethertype
If this bit is set, all messages with 0x8876 Ethertype are accepted. If this bit is clear, messages of this
type are ignored.
1 = Accept Emware messages.
0 = Ignore Emware messages.
FIPV6 — Internet Protocol Version 6 (IPv6) Ethertype
If this bit is set, all messages with 0x86DD Ethertype are accepted. If this bit is clear, messages of this
type are ignored.
1 = Accept IPv6 messages.
0 = Ignore IPv6 messages.
FARP — Address Resolution Protocol (ARP) Ethertype
If this bit is set, all messages with 0x0806 Ethertype are accepted. If this bit is clear, messages of this
type are ignored.
1 = Accept ARP messages.
0 = Ignore ARP messages.
FIPV4 — Internet Protocol Version 4 (IPv4) Ethertype
If this bit is set, all messages with 0x0800 Ethertype are accepted. If this bit is clear, messages of this
type are ignored.
1 = Accept IPv4 messages.
0 = Ignore IPv4 messages.
FIEEE — IEEE802.3 Length Field Ethertype
If this bit is set, all messages with 0x0000 to 0x05DC Ethertype are accepted. If this bit is clear,
messages of this type are ignored.
1 = Accept length field messages.
0 = Ignore length field messages.

Figure 11-6. Programmable Ethertype (ETYPE)
Read: Anytime.
Write: Anytime, but the user must not change this field while EMACE is set. Changing values while the
receiver is active may affect the outcome of the Ethertype filter.
ETYPE — Programmable Ethertype
This 16-bit field is used to program an Ethertype value to be used for the Ethertype filter.
